Feature request

Which Nextcloud Version are you currently using: Hub 9 (30.0.2)

Is your feature request related to a problem? Please describe.
Essentially we can only identify Discord channels by name, this leads to many problems for users of most Discord servers where unicode symbols and emojis are used within the text names. Also mentioned here: nextcloud/talk_matterbridge#71

Describe the solution you'd like
We can specify the Server ID as an integer like 1187942610669686868 and should be able to do the same with channel ids rather than specifying the name.

Describe alternatives you've considered
None because there's no alternatives.

Additional context
This has been a problem for almost 2-3 years now since it was reported and seems like a very quick and simple fix.

Specifying ID:1234567890 should work
